Biospecimen Retention:   Samples Without DNA

serum, plasma, urines


Enrollment: 97

Study Completion Date: June 2010
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Detailed Description:

Predictive factors of recurrence of ACS are not well determined. Platelet aggregation and leucocyte activation seem to be involved in the pathogenesis. The aim of our study is to compare SIPA, platelet activation and platelet-leucocytes aggregates on the onset of the ACS and 3 months later in 2 groups of patients scheduled for a first episode of ACS or recurrent ACS .
